Which studs enter water jackets?

[Johnny Dart]

Hey fellas,
I am about to switch exhaust manifolds and was wondering which studs enter the water jackets on the heads?

Trying to swap without draining the coolant.

Thanks.

The frontmost and rearmost studs enter the water jacket. I'm assuming you're talking about a small block?

Oops.......Correct,small block.

So that would be a total of 4 studs correct?

Front 2 and back 2.

Thanks
